PROBLEM TO BE SOLVED: To exclude loss time of support pin change, which is caused by the change of kinds of substrates, and improve productivity, by installing a second plate provided with a coming-off preventing hole with which any of support pins can engage from the axial line direction for insertion and extraction, which pins are positioned by positioning holes. SOLUTION: For positioning, a reference pin 12 is used in common. A substrate positioning pin 12a in the lower end is forcibly inserted into a positioning reference hole 13 of a printed board 1 from above, and made to engage with a positioning hole 11a formed in a base plate 11. Thereby the printed board 1 is positioned to a specified position of the base plate 11, and stably held. Hence a necessary number of support pins are easily and accurately positioned, in a short time, to the respective retaining positions. By the positioning holes, each of the positioned support pins is prevented from coming off, and the support pins in the positioned state can be handled without wobbling and coming- off.
